HAMM 3 CURTAIN CONSTRUCTION Filed Oct. 14, 1952 Patented Jan. 1, 1935 "This invention'hasto d9 H V assemblies of the type commonly "iisedjin' utomobiles, in which the curtain is mounted one. spring wound roller and -ccrds are employed at the'sides of the curtain in sliding engagement with a batten in a hem in the, bottomeof the curtain for guiding the latter; f h QK'I'he primary object ofj theinve'n ionTis to provide, in an assembly of the type, described, novel cushioning meansfor bringing the curtain to astop quietly without shock or'inju'ry when the curtain is released and allowed to roll all the way up under the action of the spring inth'e roller.

While the foregoing; statement is iridieative in a: n l, war o t e na o .t eii i ntion; other more specific objects and advantageswill be apparent to those skilled in the ia r uporl a full understanding of the construction," arra ment and operation of the cushioning means.

Three slightly'diiferent embodiments of the invention are presented herein by way of exemplification, but it will of course be appreciated that the invention is capable of being embodied in still'other structurally modified forms coming equally within the scope of the appendedclaim.

In the accompanying drawing:

Fig. 1 is a front view of a window curtain assembly equipped with the improvement of the invention;

Fig. 2 is a partially sectioned one of the ends of the batten;

Fig. 3 is an end view of one of 'thesupporting front view of brackets;

Fig. 4 is a front view of the bracket shown in Fig. 3; r g

Fig. 5 is a horizontal section, taken on the line 5-5 of Fig. 2;

Fig. 6 is a partially sectioned fragmentary front view of an assembly which embodies a The form of the invention which is s own in Figs. 1 to 5 inclusive will first be described. In I the ends 23 of the batten 24 are flattened out horizontally and provided with apertures 25.

those views a window curtain assembly is illustrated which includes a soft flexible curtain 10, a spring wound roller 11 on which the curtain is mounted, brackets 12 at the ends of the roller for rotatably supporting the latter, a batten 13 in a hem 14 in the bottom of the curtain, and guide cords 15 at the sides of the curtain which ant pbnsrnuorron man',miiiyas itfi arse" 1 Adlake Company Chi 1 means 6f taeks b Ill. aporporation of r 1e iswsrere ra ly ade r etaLfafid the ar prbviqeeg with it fi'at "'smairrubber tubes h sitidnsz-Ihe -tubes were] ct-jshort distance above and belQw-the groove at 18* in order to inter; "tlfiftl'i fI'h guide ooldS through the rubber-'g tubes' 17, 'il'gagement "with' the latter, the cords are attached by fewsf ie tof 'the flframe'woi'k of the w: dow-adjac'en the' jlower-" corners of the atte The upper endear "mana es-=15 are threaded 'thrdughapertured ears" 20 "which 'p'ro -j je ct" 'nniizontenyrrem th e -lower portions or the brackets" "12-'-i ntd it *directly-abovejtlie f I m rten; Above the ears 20 the cor s arethr'ead'e'd through small hb1es 21 in the brackets behind the heads of'tit'l ee' jth r w r latter and are securely knotted at 22 against the brackets to prevent withdrawal. The cords;

of course might be knotted just above the ears manner shown.

When the curtain is released inorder to 1 permit the .same to move up into its fully raised position under the action of the spring in the roller 11, the cords will serve to guide the upwardly projecting rubber tubes 17 on the ends of the batten 13 into centered abutment with the ears on the brackets 12, with the result that the batten :and curtain will come to rest quietlyin a horizontal position without any appreciable jar and without any danger of the edge portions of the curtain being mulchedbetween any sharp contacting parts of the batten and brackets. The rubber tubes 17 not only cushion the batten and curtain in bringing the same to rest but also are preferably so arranged as to prevent any metal-tometal contact at the time, of impact. The members 17 are preferably made of rubber, in the form of eyelets, but they may be made of other materials, in the same or different forms.

In the modification which is shown in Fig. 6,

Theapertures 25 are preferably made only large enough to accommodate thevertically extending guide cords 26. In this form of the invention, the desired cushioning effect is again obtained by the use of rubber eyelets 27 which are sewill guide the flattened ends of the batten 24 into centered abutment with the lower ends of the rubber tubes 27, and the curtainiandibattent' without any will be brought to rest quietly a Wear or tear.

The modification which is shown angst and 8 resembles that which is shown in Figs.

The upper ends of the guide cords 36 are passed through apertured ears 37 on the rear portions of the caps 33 and are knotted behind such portions in concealed positions. r

The cushioning elements are shown as being of tubular formation butotheniormations are of 7 course contemplated. ,The cushioning elements may be manufactured at very little cost ,ami may be easily inserted or replaced by merely eollapsir g them and then passing them through the"ape'rtures in the batten or brackets while 51111 8 collapsed eondition.
